Today I installed the latest Nik Collection version (I think 4.3) on my PC (Win 8.1 64bit).
It now says, when I try to run Viveza or Silver Efex, that he cannot find the SetThreadDescription point in
C:\Program Files\DxO\Nik Collection\bin\DxOFramework.dll that allows him to carry on.
All other plugin run fine (I use that along with DxO PL 4).
I deinstalled and reinstalled several times, same issue.
I did tell him when deinstalling to keep the presets.
